2001 Ford F-150 security

[Mforrest327]

My dads '01 ford is having issues. It will start and run just fine and out of nowhere it will just die. If you turn the key on and the Theft light is blinking...it wont start. If the THeft light comes on then goes off then it will be fine but will die at anytime. It aint the key since its almost brand new. Can you turn this system off anyway? Fuse removal?

Does your dad have a chip in his f150? If not then the harness to teh computer is loose.
